Robert Downey Jr. Shares First Photos of His Three-Month-Old Son, Exton Elias!

Although he stopped by The Tonight Show to talk with Jay Leno about his new superhero flick The Avengers, Robert Downey Jr. couldn't help but promote something a little bit more important to him — his three-month-old son, Exton Elias!

The actor, who first played coy about showing off baby photos, finally caved and shared two pictures of his son with Jay and the audience.

"I would get in huge trouble. I have to exercise just a little restraint. I'm sorry. I mean, if you want me to… I will," Robert joked to Jay, before the late night host took advantage of the situation and debuted a photo of Robert's wife Susan holding baby Exton. "He's so darn cute, isn't he?" proud daddy Robert said, adding, "You get one [picture], that's it. Unless of course, you want to see another one?"
